Pyknow is Deprecated, Need to Migrate from Pyknow

[imakashsahu]

Hi there,

I was playing around with the script and found that the Pyknow is no longer supported and is deprecated and should be migrated to a new library to get the script running

I updated the script with Experta library and tested the script it works fine.. and even created a PR
